Hi there,

I've got a MY2005 Impreza WRX with PPP and a Bailey direct fit Dump Valve (so far). Last night I was gunning it and the engine shutdown. It restarted with the malfunction warning light on for a few miles but then it went out. There was no apparent loss of power after restart but now I'm convinced its not right. I might just be paranoid so its going for a diagnostics check.

Any ideas why it shutdown ?? I'm guessing it may have been overboosting and the fuel cut-off was tripped.

ewan

And its running on Optimax

 

should be under warrenty take it back to garage. lol
